A float operated fuel vapor vent valve has body structure with an annular mounting flange formed of material weldable to a fuel tank and the flange is spin welded to the tank. The float has surfaces thereon which slidably engage corresponding surfaces in the float chamber to prevent relative rotation of the float with respect to the valve body during spin welding. An optional pressure relief valve in the vent outlet also has surfaces slidably engaging the vent passage to prevent relative rotation during spin welding.

Fuel vapor vent valve and method of attaching same to a tank

A method of mechanical twist lock attachment of a pass-through valve or fitting over an aperture in a plastic fuel tank having an embedded vapor barrier layer. A ring having circumferentially spaced internal lugs is secured to the tank by weldment around an aperture in the tank wall exposing an edge of the barrier layer. A seal ring on the pass-through is located in the aperture to seal the exposed vapor barrier edge. Outwardly extending projections on the pass-through attach the pass-through by twist locking engagement with the projections on the ring.

Mounting a pass-through on a plastic fuel tank

A fuel level sender () for signaling liquid fuel level in a fuel tank (). An enclosure () forming a hub of the sender provides an interior that is hermetically sealed against intrusion of fuel vapor and liquid. An actuator () is positionable on the enclosure exterior in correlation with liquid fuel level. A movement () within the enclosure interior follows the positioning of the actuator. An electric circuit element () within the enclosure interior is operated by the movement to provide an electric characteristic for transmission through the enclosure to signal liquid fuel level. A bottom reference rod () and stop () position the enclosure circumferentially within its mounting in a fuel pump module to cause the circuit element to signal zero fuel level when the stop is on the tank bottom wall and the actuator is in position corresponding to zero fuel level in the tank.
